We had a recent 5 day stay at the Caves. As a religious reader of trip advisor I felt after reading the reviews this place would be awesome. For the most part it didn't disappoint. Here's my take in a no particular rambling order.
Pros:
We arranged transportation from the hotel from the airport. We thought it was very good. We got delayed 2 hours in customs and there was our driver waiting for us. Check in was nice and easy and the first drink on arrival was stout. With nothing to eat my wife was getting tipsy fast!

The views are stunning and the property is every bit as beatufil as it looks on the website.

The staff does a wonderful job. Servers are friendly. We thought the food was fantastic. Some of the best we've had. Had the combo for every meal. Something different every day/night. Wife loved the dirty bananas. We had a private cave dinner and the staff does a wonderful job making this a very memorable experience.

Paul, who is the lifeguard/cliff diving expert, was fantastic. He took us snorkeling and was always around to offer help. Hats off to him. The cliff jumping/diving was awesome.

The Spa is open air and really nice. I believe it was Michelle whom my wife "fell in love" with. She did a remarkable job. We had booked a couples cave massage but was weathered out to large waves crashing in. I'm sure we would have liked that.

I encourage you to "get to know" your fellow Caves guests. To Eric and Leigh (sp?) what a neat couple. Joy, my wife sure enjoyed your company!

We toured the villa and it looks really cool!

Cons: Not many here by the way.
The outdoor hot tub was not working when we were there.
The private hot tub was neat but I think it needs updated. Jets don't seem to work very well.
Our room was very clean but was disappointed on how many times we were interrupted in our room by the cleaning service. Several small/private places we stay will only have maid service come when you have left the room.
Room service for breakfast had to be ordered the night before. I didn't like to have to make a schedule.
We booked the Stardust for complete privacy. It just wasn't as private as I had hoped. When tour buses stop on Wednesday and Saturday you have "several" guests right outside of you door. When I stepped out onto our deck with not much on, I'm sure the tourists were more traumatized by the incident than I was. Just to your South is the Lighthouse. There are several dogs on that property that must sleep most of the day as they howl most of the night. For this reason alone I would probably book a different room. Steps in the Stardust to your room are narrow. I also found out I prefer a bathroom on the same floor as my bedroom.

Would I reccomend the Caves to others? ABSOLUTELY! I probably had unrealistic expectations on this trip. Our last 2 trips to Mexico we were so "blown" away it probably wasn't fair for this one! By the way I took the time to visit another property called Jakes that is owned by the same company. It's located on the South Coast. It looks really cool. We might head there next.

My husband and I just got back from The Caves. We were celebrating our honeymoon. Overall we had a very nice time at The Caves. The food is GREAT (the best ever was lobster and steak night), drinks are good and the staff is friendly. Paul and Imron are especially awesome and friendly. We stayed in Two Birds- the outdoor shower was awesome and the jungle view was beautiful. I can honestly say that I didn't really miss the ocean view since all we had to do was step outside to see the ocean. If you are on a budget I would definitely recommend booking Two Birds as opposed to the more expensive ocean view properties. Caves dinner in #2 was awesome... something you need to experience in real life as pictures don't do it justice. You MUST watch the sunset each evening... amazing.
There is room for a few improvements, though minor, they would have made our stay a bit more enjoyable. Many of the umbrellas were on their death bed, and when the wind came through staff asked us to close them. My husband had to stay out of the sun due to a recent surgery, so closing the umbrella forced us to go back inside. Again, minor, but if the umbrellas were in better shape we would have been able to stay out like we wanted. Another suggestion is for the Caves to have an activity listing. Sometimes there were events held at the Sands (like a cocktail hour) that my husband and I didn't know about until after the event. The Caves also offers yoga, sunsets in the hot tub, snorkeling, etc. Staff tells you everything when you first arrive, but it's so much information to remember so it would be nice if it was written down in the room somewhere for us to refer to throughout the week. I do think the Caves is a bit overpriced. I do think you are paying Ritz Carlton luxury prices for a 3 to 4 star facility.
When booking at the Caves you need to know what you are getting into. It is extremely quiet- we were in bed by 9 pm each night. There really isn't a lot to do- we ate and drank a LOT, sun bathed, napped and read lots and lots of novels. We were there for 6 days but would have been content with 4. We noticed most couples stayed 3-4 days and I think that would have been enough... after 4 days it got to be a little boring. I would recommend The Caves to those looking to recharge their batteries and to escape from technology and normal life.
